Patent GB-491522-A (GB)
Title: Improvements in or relating to the manufacture of synthetic lubricating oils
IPC: C10G50/02
Filed: 1937-03-04
Abstract: In making lubricating-oils by condensing an aromatic hydrocarbon with a chlorinated aliphatic hydrocarbon of high molecular weight in the presence of Al or AlCl3 as catalyst, the product is treated with an amount of water less than, or not greatly exceeding, that theoretically required to convert the AlCl3 present to Al(OH)3, and is heated to a temperature above 200 DEG  C., and the oil isolated by filtration, extraction or decantation.  If Al is used, the HCl liberated during the condensation transforms some or all of it into AlCl3.  The preferable temperature is 250 and 300 DEG  C.  The condensation product may be allowed to separate into two layers, one or both of which may be treated with water.  Instead of water, a hydrated metal salt such as BaCl22H2O, CnSO45H2O or Na2SO410H2O may be used the amount of salt necessary being deduced from its water content. In an example, 1000 parts of chlorinated paraffin wax containing 29,3 per cent Cl are reacted with 1000 parts of benzene and 90 parts of anhydrous AlCl3.  After separation into layers, the lower layer is treated with water or Glauber's salt to convert most of the AlCl3 to Al(OH)3.  On distilling off the benzene, a red-green fluorescent oil can be decanted from the granular residue.

Title: Improvements in and relating to conveyors and elevators for hay, straw and like loose material
IPC: A01D87/02
Filed: 1942-05-19
Abstract: 557,189. Agricultural conveyers. WAKEFIELD, T. May 19, 1942, No. 6820. [Class 78 (i)] A conveyer or elevator for hay &c. comprises a reciprocating carriage d carrying pivoted tines a which project through slots in a floor board b supporting the hay. The carriage d runs on wheels e riding on rails f, and is moved to and fro by connecting rods g working from a rotating crank-piston &c. The tines a are pivoted at their lower ends c to the carriage frame d<SP>1</SP>, and are coupled together by links h. They are capable of adopting three positions, viz. a vertical operative abutted position in which they push the hay forward with the forward movement of the carriage, an inclined inoperative position, shown in broken lines into which they are forced on the backward movement of the carriage by the reactive pressure of the hay, and a completely submerged position to which they are brought when the carriage is to reciprocate ineffectively. The latter position, in which the tines are turned more fully down forward, is permitted by a pivoted stop lever which normally prevents such downward swing, but which can be turned out of operative disposition either manually or automatically. Two carriages d may be coupled together by rods, and function one on a substantially level plane, and the other on an adjacent incline to feed the hay to the upper level.

Patent GB-609088-A (GB)
Title: Engine starting device
IPC: F02N5/02
Filed: 1946-03-05
Abstract: 609,088. Spring motors. SOC. ANON. A. CITROEN. March 5, 1946, No. 6872. Convention date, Feb. 27, 1945. [Class 10] [Also in Group XXVII] A device for starting engines or for similar purposes consists of a torsional spring motor comprising a number of rubber rings S, Fig. 1, connected together in series, so that the total twist is equal to the sum of the individual angles of twist, the first ring 1 being rigid with a manual or electric tensioning device and the last ring 6 with a normally locked member 7 coupled by a one-way clutch RL to the crankshaft or driven part M. The rings are vulcanized at their inner and outer diameters to metal connecting-sleeves. The tensioning means may consist of a hand-driven pinion p coacting with a pawl C or a worm gear may be driven through a ratchet coupling from a spring- returned cable 8 passing over a drum 9. The locking pawl V may be held in engaged position against a pull-off spring r by a keeper L and lever M. When the keeper L is actuated by the release mechanism through cable 32, the spring r disengages the pawl to permit recoil of the rubber rings. The spring R subsequently re-engages the pawl. In a modification, the release mechanism is controlled by the clutch pedal. In a further modification, Figs. 6 and 7, keeper L and lever Mare controlled by solenoid cores 25 and the tension applied to the rings is made dependent on engine temperature. For this purpose a liquid capsule 12 in the engine sump 13 controls a capsule 14 carrying a contact 15 in the solenoid circuit, a second contact 16 being carried by a rod moving axially with a worm 29, which compresses a spring 28 in accordance with the torque applied to the system by a motor 27 or by hand. An electric relay 20 is arranged so that energization of the solenoid 17 continues through coil 20 and contacts 21 after the starting torque has been exerted and the contacts 15, 16 disengaged, thus preventing immediate return of keeper L. The contacts 21 may be broken by a winding 22 energized by the battery charging current after the engine has started or by the current in motor 27 if the engine fails to start and a new attempt is to be made.

Title: Improvements in and relating to fluid-operated presses
IPC: B21J15/22
Filed: 1941-06-05
Abstract: 549,115. Hydraulic presses. BROOM & WADE, Ltd., and CUTHBERT, R. A. June 5, 1941, No. 7109. [Class 69 (ii)] A hydraulic press for riveting, punching, shearing, or pressing is operated by liquid from an intensifier or the like which effects the approach stroke by the action of the liquid on an hollow auxiliary piston 34 connected to the power piston 25 which is constructed with apertures which permit the liquid to pass from one side of the power piston to the other during the approach stroke. The piston rod is formed with an enlarged head 27 which can slide in a flanged cylinder 26 secured to the power piston 25, and a rod 41 attached to the head 26 acts upon a ball valve 40 at the end of the approach stroke. This valve normally prevents the pressure liquid from acting upon the upper side of the piston 25, but when the work is engaged between the tools 13, 14 the head 27 moves relatively to the piston 25 and in addition to opening the valve 40 it closes the connection between the two faces of the piston so that the pressure liquid acts upon the upper face of the piston to effect the working operation. Liquid can pass from the working cylinder to an outer casing 15 via apertures 24, and this casing is normally filled with liquid and acts as a reservoir and is fitted with compensating means in the form of air-filled resilient members such as a number of hollow rings or balls, or, as shown, an annular V-shaped trough member 18 of indiarubber. A return spring 43 retracts the piston 25 when the pressure is withdrawn. The ball valve 40 may be replaced by other forms of valve.

Title: Method for the production of a catalyst
IPC: B01J23/755
Filed: 1947-03-18
Abstract: A catalyst containing active nickel, nickel silicate and a small amount of chemically-bound sulphur, for conjugating double bonds in drying and semi-drying oils including fish and train oils, is prepared by subjecting a mixture of nickel silicate and a nickel compound containing sulphur, e.g. nickel sulphate, to reduction with hydrogen at 300-500 DEG  C.  The active nickel may be produced by the reduction of the silicate or, alternatively, another nickel salt, e.g. the hydroxide or carbonate, which on reduction yields active nickel, may be added to the silicate prior to reduction.  The nickel silicate may be produced by reacting a nickel salt with water-glass solution or by boiling kieselguhr with soda solution in the presence of a nickel salt.  After reduction the catalyst is displaced with an inert gas, e.g. carbon dioxide, and kept in oil.
